\NVENTOR WITNESSES ATTORTEY HAROLD s. MAHAN, o r EFrrne AM, Kansas;

- ADJUSTABLE BOOK-MARK 3120031); If r To all whom .z't may' concern:

Be it known that I, HAROLD MAriAN, a

citizen of the United States, residing at Effingham, in the county. of Atchison, in the State of Kansas, have invented a new and useful .Adjustable .Book-MarkfRecord, of

- and in which like characters of reference inwhich the following is a specification.

I This invention relates to book marking de-.

vices and more particularly to an adjustable bookmark adapted for use particularly by students and scholars studying from text books or the like. and to whom a certain. number of pages. in the text book are as: signed for each lesson in the course of instructions. 4 a V One of the objects of the invention is-to providev a plurality of adjustable elements associated with the book mark and provided with; certain indicia whereby the pages in; thetext -bookmay;be indicated to designate the point .at which the lesson beginsand ends; the page Which is reached at the end of the month and other similar information relative to the text which thestudent is or-.

dinarily required to remember if notes are,

not previously made. I

The inventlon-also alms to provldean adjustable book mark thatw-ill include a device for indicating tov the student the next subject matter for the subsequent instruction.

The invention also includes the provision of a structure whereby the adjustable elements of the book. mark. will be held .in. proper fixed position when the device has been properly adjusted and which will serve during this fixed period,-as a book mark for the volume which is being used.

The invention also aims to provide a book.

mark that will be extremely simple in constr'uction, durable and well adapted to stand the rough uses to which devices of this char: acter will be subjected. f For a full description of the invention and the advantages and merits thereof, referwoe is to be had to the following description and the accompanying drawings, where: in is illustrated the preferred form of my 1nmention, in which; 5

" provided with a transverse slot/1 for the re-';

these ends ofthepanels together. Near one ofv the longitudinally curved edges of the frontpanel 1, and substantially in the center of the panel, Ihave-inscribed a V series of titles such as Draw map, Learn certain. lessons to bestudied by the student. It will be understood that this list ofdiiferfront elevation of a book mai atented l ec. 11, 191.7. g

Referring to the drawing wherein is illustrated thepreferred form'of my invention,

1 has its longitudinal edges curved so that iti s substantially elliptical in formation, one V end being drawn; to a point as indicated at .2

for .the purpose of providing a locking tongue for. the front panel 1. The back panel 8 is of substantially the same form as the front panel 1 excepting its end is slightly V elongated and, rounded as indicated in F ig.

1 ofthe drawingandthis rounded end is 1 ceptionjofthe tongue to lock the two panels I together.,,,;,-l he opposite ends of the panels are held togetherby a tape orribbon 5 passing through convenient slots 6 for holding poem etc. these being the subject matter of ent subject matters may beextendedlto any desired-length according to the curriculum and in order that the proper subject matter point element 7 shown to advantage in- Figs.

and lower endsof the list of Subjects, I have posed .on the front panel. The ends of the.

pointer elementare then disposed between the front and back panels and one end is provided-with a head or enlargementforthe purposev of preventing thepointerelement from :being accidentally withdrawn from the slot after once being placed in position, A5105 projectingpointer 9 -is formed on, onelonj gitudinaledge of the pointer element 7 and I 1 this pointer 9 comes lnto registration with any of, the inscribed subject mattersion the.

adjacent portion of the front panel. 119 I .may be correctly indicated and remembered I have provideda longitudinally adjustable pointer may be longitudinally .adjusted to indicate any one of the subject matters which is to be studied by the student.

In the remaining portion of the panelI have provided a series of slotslO which are arranged in pairs and slightly vertically spaced apart. The pairs are arranged in groups'of three as will be apparent from a consideration of Fig. 1 0f lthe drawing and each pair of slots receives one of the adjustable indicating elements 11', which consists of an elongated strip ofsuita'ble thin material havingits surface inscribed with a series of numbers runningin numerical order from 1 to 0. It will be obvious that it is merely necessary to adjust the elements ll to properly indicate certain numbers" in each group ofthree to indicatewhere a certain lesson'is'to begin,'where it is to end, the page ln the volume whiclr" should be reached bythe end of the month," and-certain pages where prescribed prob lems are to be studied ormemorized; As shown 'in Fig. 3', one of theadjustable elem'ents ll is shown in-crosssecti'on and it will be apparent that-it is onlynecessary'to unlock 'the' tongue 2 from the rear'panel and to lift the front panel so that access maybe gained to the strip of material forming the adjustable elements." These may then be gripped bythe fingers and moved'to the de'-' sired position and the enlarged arr-ow headson the ends of the strip willprevent acci dental --witlidrawal from the slot.

It will be understood, of course, that the device is constructed; from comparatively thin material and'will lie flat between the pages of abook' so that it will act as an excellent book-mark in addition to the instructions toll'ie'stu'dent relative to the assignmenti Vith this device it will'be unnecessary to make note of the assignment.

From the foregoing it will be observed that a very simple and durable bookmark has been provided,the detailsof which embodythe preferred formi I desire it" to be; understood, however, that slight changes in the minor details of 'constructionmay be made without departing from-the spirit of the invention orsthe scope of'the claims hereunto appended;

hat I claim is 1. A book-mark of the character described comprising a pair of panels" I arranged in superposed -relation',. means for locking the panels'at one end, said-means including a" tongue formed on'one of the said panels, the other panel having a slot for the reception of said tongue, andadjustable marking elements mounted on-the front panelfthe latter being'provided with slotsto receive thej-el'ement; the said' element' having. cermovement, the ends of the said strip being disposcdbetw'een the panel whereby the" 75 strip will.beheldremovable when the panels are in relatively closecontact, one of the said panels having a tongue' -engageable with the other panel t-o' hold the two panels together? 'A- 'book marking'device comprising a pair of superposed-panels of substantially the same configuration, the end of-the back panels being elongated and slightly round ed', the rounded end having atransverse slot '85 providedth'erein, the 'said front panel beings pointed at its end and adapted to providea tongue for reception in -thesaid slot, to lock the'said'panels together, and aplurality of indicig strips mounted on thefrOI- tQQO panel; the latter having a plurality of; slots for the-reception of the said stripswhereby certain portions of the strips" may bfe' e posed.
